Windows are important to a home’s energy efficiency, ventilation, curb appeal and natural lighting. They’re a significant investment in your property, so you have to make sure they’re protected by a warranty.

In this article, here are the things you should look for when reviewing your window warranties.
Product Warranty
This warranty mainly covers any faults or defects the window may have during a set coverage period. Some of the common problems that this warranty covers are faulty window seals, warped frames and defective mechanical hardware. Different manufacturers provide different terms and coverage for their products, but all of them are common in the sense that they replace and repair any defects or issues resulting from manufacturing errors. Keep in mind that product warranties typically do not cover any damage caused by negligence, poor handling, acts of God and abuse.
Workmanship Warranty
Workmanship warranties cover any labor costs needed to correct installation errors. From window diagnosis to the professional skills needed to repair or replace parts of your window, most workmanship warranties address the basics involved in the installation and removal of a window. Different contractors offer varying lengths of coverage. Some provide a lifetime workmanship warranty, which means they will the installation is covered as long as you own and live on the property. It’s important to keep in mind that most of these warranties only cover installation, repair and removal. Any other maintenance costs incurred – like the costs for caulking materials and disposal of waste material – typically have limited to no coverage.
